History on 2 sleds: both are '15 XF 137's, one 8000 and one 6000. Bought as leftovers fall of 2015 and had 300 miles put on last winter. This fall noticed oil on floor in garage under each and the chaincase level had dropped in the sight glasses; the 8000 slightly worse than the 6000. Dealer did the seals under warranty just before it ended in October 2016. Both sight glasses were full (no visible oil level in either - not sure how far above sight glass oil was, likely not by much). Dealer is a great dealer.
So we just got back from our first 85 miles this year and noticed both are down again. After sitting in heated garage drying for 4 hrs, again the 8000 slightly worse than the 6000 (6000 is just barely below the top of the sight glass). But were no visible oil leak on the floor under either since they were brought home mid October. Neither had any visible oil in the belly pan dip under each case either.
I did notice some oil tonight on each sled right under the rubber fill plugs and just below that (where my finger is pointing) as pictured. There's no visible oil drip lines or oil run lines down the casing.
I will be contacting my dealer again but it's a $200 trip out there on gas every time (6 hr round trip and would require 2 trips). So questions are:
1. Anyone have a similar experience?
2. Is it possible for the rubber fill plug to leak as oil is splashed around or is this likely dribbles from when they filled it?
3. Since this is their first run since being brought home and the only time they've moved is from garage to trailer (20 feet) a couple times, can oil get splashed around the chaincase and puddle up in any little areas that it won't drain back down to the same level when it is first filled now that they've been ran for 85 miles? (may be a stupid question but worth asking)
First pictures are when we first got home. One with yellow dot above sight glass is 8000 and the blue dot is on the 6000. Second pics of each are after sitting in garage for 4 hrs drying off at plus temps. Last pic is the one of the oil puddles under the fill plug. Both have similar puddles.
It's not about how fast you get there; it's about the fun you have along the way!
